I don't realy like those tactics as well.
I would not promote it. But most ppl want to see 35-40-45 per trial. Well this way they can afford it.
I prefer site like nastydollars, cleaner, and a HUGE memberarea. When you sell those memberships you will be pretty sure members will be happy and want to buy more porn one day
When they join a PPS program with all these prechecked, and terms about canceling etc etc, they will feel screwed, and might not buy porn again..
Just my
